Hand-held road marking machines

The largest selection of road marking machines can be found in the range of hand-held machines. But even here there are many decisions to make. Should it be a machine with a diaphragm or piston pump? How much pump power is required? Which materials will be used? Will you be using the machines outdoors or indoors? With a gasoline engine or an electric motor? One wheel at the front - two at the rear or two wheels at the front - one at the rear? Where is the suspension of the paint gun located? With balancing wheel (marker) or without?
